鲁教版八年级上册第三单元过去进行时

1、.教学部备课笔记学生姓名：年级：学校：学科：英语课时：本节课教学目的：过去进展时本节课重点：过去进展时的根本构造，否认句，一般疑问句的变化，本节课难点：过去进展时与一般过去时的区别，when与while的区别课堂内容呈现：过去进展时的用法：表示过去某一时刻或过去某一阶段正在进展的动作过去进展时的根本构造：1 主语+was/were+动词的如今分词doing+其他 主语单数用was，复数用wereMy mother was cooking dinner at this time last night.否认句:was/were后加not My mother wasnt cooking dinner

2、 at this time last night. 一般疑问句：was/were提到句首 Was your mother cooking dinner at this time last night?肯定答复：Yes,人称代词+ was/were No,人称代词+wasnt/werent肯定句变为疑问句时第一人称要变为第二人称动词如今分词变化规那么： 1 普通单词直接加ing 2 以不发音e为结尾的词去e加ing 3 以“重读闭音节为结尾的词双写最后一个辅音字母加ing 闭音节是两个辅音中间夹一个元音 4 die-dying lie-lying tie捆，绑，系-tying 元音字母：A E

3、I O U时间标志词：then那时，at this/that time+过去的时间，at +点钟+过去的时间when与while区别：when是at or during the time that, 既指时间点，也可指一段时间，while是during the time that，只指一段时间，因此when引导的时间状语从句中的动词可以是非延续性动词，也可以是延续性动词，而while从句中的动词必须是延续性动词。 延续性动词指的是能延续的动作when 说明从句的动作和主句的动作可以是同时，也可以是先后发生；while 那么强调主句的动作在从句动作的发生的过程中或主从句两个动作同时发生。 由wh

4、en引导的时间状语从句，主句用过去进展时，从句应用一般过去时；假如从句和主句的动作同时发生，两句都用过去进展时的时候，多用while引导，一般过去时与过去进展时的区别：一般过去时往往表示某一动作已经完成，过去进展时表示动作在持续或未完成。She wrote a letter to her friend last night.信已经写完She was writing a letter to her fiend last night.写信的动作持续了一晚上，不一定写完了例题考察题型1 选择1.
